Getting a Trekker or other GPS system for mowing the lawn is a bit extravagant. Might as well get a robotic lawn mower at that point. But it might work.
Here's a much cheaper way, but doubt you will like the solution. Just do one of those invisible fences for dogs. Then where the receiver on your arm. Whenever you get close to the edge of the field, it would shock the hell out of you. They are distance modulated as well, so you could tell how close you are getting to the edge by the strength of the shock you are receiving. *GRIN* -- Blue skies.
